Phase precession in the human hippocampus.

01] Coronal T2 MRI scan merged with post-implantation CT scan showing location of electrodes (white circles) in the human hippocampus (red).
02] Heat map of spatial phase precession for one human hippocampal neuron. Each pixel represents a location in space in the virtual environment. Colors indicate the theta phase action-potentials occurred at as the subject moved through a particular location; precession is represented by the gradient of colors across space.
03] Overhead view of the virtual environment, showing the six navigation location goals.
04] First-person view of the virtual environment.
